This invention relates to a mop wringer designed to be attached to a mop bucket and has for its primary object to provide an improved wringer device'which may be used in association with any v suitable bucket and which maybe grip the mop wringing the same. e I l p The invention broadly contemplates the provision of a base carrying a frame comprising a fbetweenwhich the mop 'bucket'may be positioned, I signed to carry a roller. Pivotally connected to the bar member at one end ofthe same is a vertically shiftable arm which normally extends in an upwardly inclined direction over the top member of the frame and which is designed to be swung downwardly to bring a roller. carried 'thereby into contacting relation'with a roller carried by thesaid top member. A spring normallymaintains the vertically shiftable arm in raisedposition and attached to the free end of the'arm is a foot,

operated lever by means of which the arm is drawn downwardly in the, manner de-' scribed. I r v A further objectof the invention is to .provide a mop wringer of the above described character which is of simple construction, strong and durable and inexpensive tomanufac'ture. V

The invention .will be best understood from p a consideration-of the following detailed description taken in connection with the accompanying drawing forming. a part of the present invention however, toany strict conformity with theshowing of the drawing butmay be changed or modified so long. as such changes or. modifications mark no material departure from the salient features of the invention as expressed in the appended claims. In the drawing Figure 1 with the understanding,

1s a view in side elevation of the mop wringer structure embodying the present invention;

Figure 2'is an enlarged side elevational view of the connected endsof the rollers;

easily and quickly operated to. preparatory to squeezing or pair of spaced upright members,

and a transverse top member de-f being attached :to

that the invention is not confined I Figure-3 is a sectional view through one: side member of the frame showing the manner' in which the foot lever is attached thereto; V

Figure 4 is a plan view of amodified arrangement of the mop squeezing rollers.

Referring to the drawing'in detail wherein 1 like numerals of reference indicate corresponding parts throughout the several views, the numeral 1 indicates the base of the present-mop wringer device, which base-may comprise ametal frame or disc of wood or similar 'maiterial. At diametrically opposed points the base 1 carries the upright bars 2' and-3, the upper ends of which bars are connected by afixed cross arm 1. When a mop bucket such as that shown in dotted lines and indicated by the numeral 5, is in position upon the base 1 the fixed over the open top thereof. 7

At one end the stationary bar .t-is-turned upwardly as indicated .at 6 and terminates in a hinge knuckle 7. Secured to this hinge knuckle by a suitable pin 8 is a similarly H formed endof a shiftable arm 9. .Thearm 9' overlies the fixed bar 4: of the frame and carries-a roller 10 which extends substantially the entire length of the arm, this roller coacting with a similar roller 11 rotatably mounted upon the bar 1. '1

'A suitable coil spring 12 is mounted upon the hinge knuckle 7, one end of this spring the shiftable arm 9 while the other end issecured to the fixed arm 4 or to the adjacent upright arm 3 of the frame, the spring acting to normally maintain the upper roller arm 9- in the raised position shown. v 7

At its outer end the upper or shiftable arm 9 has a ring 13- formed for connection with the upper end of a pull rod 14. The pull rod l lis mounted in vertical position adjacent the upright bar 2 of the frame in the guide eyes 15, these guide eyes'being carried by the bar 2 as shown. The lower end of the pull oot bar is extended laterally to provide a piece 16. V e

The, lower end of the bar 3 has secured thereto an outwardly extendingpedal-17 upon which one foot of the operator is placed to arm 4 will extend P 10 V ployed without departing from the spirit'of hold the frame and bucket stationary while the other foot is used to depress the pedal 16 of the bar '14 to pull the shiftable arm 9 downspring 12 has been modification wardly during the mop squeezing operation.

While an ordinary conventional type of the roller raised it is, of course,'to be understood that I do notfwish to be limited to this particular type'of spring for" it is obviousextending hinge sleeve7 through which a" suitable pivot bolt 7 is passed. I a

The shiftable bar 9 is formed atone 'endto provide a sleeve 9 designed to position upon 7 the bolt"? and operate' against the sleeve a ner as the mopplaced between the rolls.

which forms a part of the fixedv bar. The otherend of this bar 9 may be connected with a pull rod which, while not shown in Figure 4, may be mounted in the same manthat upon application of the foot of the user of theidevice to the lateral extension of the pull rod the roller 10 maybe swung down to ahorizontal position at 'one'side of the fixed normally horizontal roll 11 to grip a The rollerlO of this modified structure may be caused to assume a-raised position with respect to the fixed roller'll 'by the use of aspring device (not shown)"similar to the v spring used in connection with the preferred form, A ,7 From the foregoing description it will be readily seen that when the presentmop wringer device is in use, ample room s'provided for inserting the mop into the bucket on either side of the wringer rolls and when it is desiredto squeeze or wring out the mop it 'is positioned betweenjthe rolls and the sameare drawn together inthe manner debetween the rolls'which action will result in scribed to grip the mop therebetween after whichthe mop can be forcibly drawn from its being thoroughly squeezed out. Upon release of the pedal 16 thespring 12 will op-,

era-te to raise the upper roller and itssupporting arm 9 free of the lower roller preparatory to the introduction o'f'the mop for 'a'second wringing operation.
